Objective: To revise, translate, explore the construct validity and define the sensitivity of the Post Traumatic Stress Disorder Scale of the Child Behavior Checklist (CBCL‐PTSD). Method: Language and content experts revised the translated CBCL‐PTSD scale. This 13‐item CBCL‐PTSD‐TR scale was administered to 100 adolescents who had undergone various traumatic life events. Exploratory factor analysis was conducted. Screening threshold was determined for the final six‐item version. Results: The DSM IV‐TR construct for PTSD was reflected in the CBCL‐PTSD‐TR scale by the exploratory factor analysis and provided information for refining the instrument. A CBCL‐PTSD‐TR cut‐off score of 0.5 was an effective threshold for screening purposes. Conclusions: We were able to show that the CBCL‐PTSD‐TR scale compiled from the original CBCL scale items has satisfactory construct validity of DSM‐IV‐TR and can be used for screening adolescents with PTSD. Implications for assessment and treatment utilization are discussed. [ABSTRACT FROM AUTHOR]

Objective: This study validates the Tamil version of Impact of Event Scale among adolescents. Method: IES was translated into Tamil and 100 adolescents attending an adolescent clinic who had been exposed to diverse traumatic events completed the Impact of Event Scale along with the Child Behaviour Checklist. Appropriate analyses both at the item and scale levels were conducted. Results: In addition to adequate face and content validity, the scale has satisfactory internal consistency (α from 0.77 to 0.90), moderate convergent validity with CBCL‐PTSD scale (r from 0.22 to 0.29), and high discriminant validity with PTSD‐thought problem subscale (r = 0.01–0.10). Factor analysis replicated the two‐factor structure, avoidance factor (five items) and intrusion factor (three items), explaining 68.4% of variance. A threshold IES score of 17 was associated with 93% sensitivity and 85% specificity. Conclusions: The Tamil IES for adolescents has satisfactory psychometric properties and should be useful in international studies as well as clinical care. [ABSTRACT FROM AUTHOR]
